[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-7 As shown, it includes an installation cavity 1, the bottom end of the installation cavity 1 is connected to an alloy support layer 2, the alloy support layer 2 is fixedly connected to a pop-up structure 3, the pop-up structure 3 is connected to a limiting structure 4, the limiting structure 4 is fixedly connected to a nozzle structure 5, and one side of the pop-up structure 3 is connected to a redundant structure 6.

[0027] The installation cavity 1 is an installation cavity 1 opened on the installation surface. The alloy support layer 2 is fixedly connected to the installation plate 306 of the pop-up structure 3. The alloy support layer 2 is a fusible alloy element. When a fire occurs, it will be melted by high temperature, which will cause the pop-up structure 3 to move, and then drive the redundant structure 6 to trigger the sprinkler structure 5 to spray fire water. The limiting structure 4 limits the transmission direction of the pop-up structure 3.

[0028] The pop-up structure 3 includes an adjusting rod 301, a limiting ring 302, a sleeve 303, a spring 304, a fixing plate 305, a mounting plate 306, a splash plate 307, a fixing hole 308, and a connecting rod 309. The limiting ring 302 is fixedly connected to the adjusting rod 301, and the top of the adjusting rod 301 is integrated with a connecting rod 309. The sleeve 303 is slidably connected to the connecting rod 309, and the sleeve 303 is covered with a spring 304. One end of the sleeve 303 is fixedly connected to the fixing plate 305. The adjusting rod 301 is fixedly connected to the mounting plate 306 at the end away from the connecting rod 309. The center of one end of the mounting plate 306 is fixedly connected to the splash plate 307, and a fixing hole 308 is opened in the center of the fixing plate 305.

[0029] After the alloy support layer 2 is melted by high temperature, the mounting plate 306 loses its fixing force, which in turn releases the elastic potential energy of the spring 304, causing the limiting ring 302 to drive the adjusting rod 301, the mounting plate 306 and the splash plate 307 to pop out of the mounting surface, and the maximum pop-up distance is limited by the limiting structure 4.

[0030] The limiting structure 4 includes a fixing sleeve 401 , a connecting sleeve 402 , and a guide lug 403 . The fixing sleeve 401 is fixedly connected with the connecting sleeve 402 . The connecting sleeve 402 is surrounded by guide lugs 403 . The guide lugs 403 are slidably connected to the adjusting rod 301 .

[0031] The guide ear 403 can limit the maximum transmission distance of the limit ring 302 to prevent the pop-up structure 3 from falling off as a whole, and the fixing sleeve 401 is fixedly docked with the fixing hole 308 .

[0032] The nozzle structure 5 includes a yoke arm seat 501, a sealing gasket 502, a glass body 503, and a pipe thread 504. The sealing gasket 502 is installed in the yoke arm seat 501, the glass body 503 is installed at one end of the sealing gasket 502, and the pipe thread 504 is fixed at one end of the yoke arm seat 501.

[0033] After the glass body 503 of the nozzle structure 5 is mechanically broken by the redundant structure 6, the sealing gasket 502 loses its sealing effect, thereby causing the fire water from the water pipe connected to the pipe thread 504 to be introduced and sprayed to the outside through the splash plate 307 to extinguish the open flame.

[0034] The redundant structure 6 includes a transmission rod 601, a docking joint 602, a connecting lug 603, a through-joint lug 604, a connecting seat 605, and a metal contact 606. A docking joint 602 is provided at one end of the transmission rod 601. The docking joint 602 is rotatably connected to the connecting lug 603. The connecting lug 603 is fixedly installed on one side of the adjustment rod 301. The transmission rod 601 is rotatably connected to the through-joint lug 604. The connecting seat 605 is fixedly installed on the through-joint lug 604. The through-joint lug 604 is fixedly installed on the yoke arm seat 501 through the connecting seat 605. The other end of the transmission rod 601 is fixedly connected to the metal contact 606.

[0035] The connecting ear 603 of the redundant structure 6 will be transmitted along with the adjusting rod 301 when it pops out, thereby causing the docking joint 602 of the transmission rod 601 to rotate, causing the transmission rod 601 to slide and rotate on the connecting ear 604, thereby changing the position of the metal contact 606, causing it to mechanically squeeze the glass body 503, causing the glass body 503 to break, and then causing the nozzle structure 5 to spray fire water.

[0036] In summary, with the aid of the above-mentioned technical scheme of the utility model, an installation cavity 1 is opened on the installation surface, and the alloy support layer 2 is fixedly connected to the installation plate 306 of the pop-up structure 3. The alloy support layer 2 is a fusible alloy element, which will be melted by high temperature in the event of a fire, thereby causing the pop-up structure 3 to actuate, thereby driving the redundant structure 6 to trigger the sprinkler structure 5 to spray fire water, and the limiting structure 4 limits the transmission direction of the pop-up structure 3. After the alloy support layer 2 is melted by high temperature, the installation plate 306 loses its fixing force, thereby releasing the elastic potential energy of the spring 304, thereby causing the limiting ring 302 to drive the adjusting rod 301, the installation plate 306 and the splash plate 307 to pop out of the installation surface, and limit its maximum pop-up distance through the limiting structure 4, and the guide ear 403 can limit the maximum pop-up distance of the limiting ring 302 The large transmission distance is limited to prevent the pop-up structure 3 from falling off as a whole. The fixing sleeve 401 is fixedly docked with the fixing hole 308. After the glass body 503 of the sprinkler structure 5 is mechanically broken by the redundant structure 6, the sealing gasket 502 loses its sealing effect, thereby causing the fire water of the water pipe connected to the pipe thread 504 to be introduced and sprayed to the outside through the splash plate 307 to extinguish the open flame. The connecting ear 603 of the redundant structure 6 will be transmitted with the adjusting rod 301 when it pops out, thereby causing the docking joint 602 of the transmission rod 601 to rotate, causing the transmission rod 601 to slide and rotate on the connecting ear 604, thereby changing the position of the metal contact 606, causing it to mechanically squeeze the glass body 503, causing the glass body 503 to break, so that the sprinkler structure 5 can spray out fire water.
